ANTIRAT'TLING DEVICE Fon STORM WINDOWS'. l

. Application fled February 20,' i928.A Serial No. 255,757.

My invention relates to an anti-rattling device for storm windows of thetype hinged at the top and adapted to swing out and be held in openposition with the lower edge away from the window fra-me. The mainobject of :the invention is to provide a simple, efficient andinexpensive device in the form of a. spring device which engages a stormwindow bracket arm and a part of a window frame under tension in such amanner that rattling of parts ordinarily caused by the elements isentirely eliminated.

In the accompanying drawing, Fig. 1 is a vertical sectional elevation othe lower portion of a window frame andthe lower part of a storm windowbeing held outwardlyof the window frame and my device in operativeposition.

Fig. 2 is an approximately full size front view of my device looking asin direction of arrow A in Fig. 1, and Fig. 3 is a side elevation ofFig. 2 as seenlooking toward Fig. 2 from the left.

Referring to the drawing by reference numerals the window frame shown incross section comprises the usual sill 5, side frame 6 andwindow-parting strip 7, 8 is the lower and regular slidable sash. 9 isthe vertical strip comprising a stop for the inner edge of a st-ormwindow 10 to bear against when in closed position.

My anti-rattling device is particularly designed for the type of stormwindow bracket comprising, a pivot bracket 11 fixed one to each Ysidemember of a storm window and to which is pivotally secured as at 12 abrace bar 13 of flat bar stock as shown, said bar being looselyslidable' through a slot of another fixed bracket 14 secured on thevertical side frame 6 of the window. The free end of bar 13 is usuallybent inward as 13B to provide a finger hold and also serve as a stop tolimit outward movement of the storm window and such bar is usuallyprovided with a downward notch 13N to engage the notched part of bracket14 when the member 13B is close to said bracket, as best shown inFig. 1. It is obvious that when the bracket device described is in theposition holding the storm 5.o window out from the wall, any wind orcomparatively light air currents will shake the storm window and causethe brace 13 to rattle in the bracket 14, creating undesirable noiseparticularly at night when a storm window is usually wanted open but atsuch times being oppositeends of which extends radially and 1n oppositedirections two arms 15A and 15B of which 15A is the front arm. The frontend of said arm 15A isformed with an upward extension 15A at rightangles to the arm and the said extension formed with a hook 15A openingdownwardly.

mally in obtuse angled position relative to each other when the springis inactive (see vfull lineposition of arms in' Fig. The

free end of arm 15B is formed with a trans-` verse elongated catchmember 15B in a plane about radially out from the center of the coils 15said catch member being preferably a formation of the wire in twoparallel parts as shown in Fig. 1 and the extremity of the wi repreferably formed in a linger engaging loop 15B In the use of my devicethe hook 15A of the front arm is simply engaged over the top edge of thebar 13, arm extension 15A extenolingk downwardly and arm 15A rearward-Vly with coil 15 placed immediately below and inwardly of bracket 14with arm 15B extendving inwardly and up. Then the operator simplypresses against member 15B outwardly until the double wire arm 15B is ina plane just outwardly of the window frame 6 at which time the operatorpresses outwardly so that arm 15B can be released and member 15B willengage and be spring pressed against the outer surface of the uprightwindow frame. As the arms 15B and 15A are thus sprung toward each otheragainst the action' of spring 15 it is obvious that arm 15A bears downon bracket arm 13 and holds it solid kand in non-rattling position inbracket 14.

The device may also be designed in such proportions that when inoperative position as described arm 15B will engage the rear part oflinger hold 13B of bar 13 and thus preventing any endwise movement ofthe bar (see Fig. 1).

I claim:

The rear arm 15Bmay be longer than the front one and both nor-' 1,. Ananti-rattling device for a storm window hingedly suspended from itsupper edge and having a brace bar pivotally connected to theinnersideofthestormwindow and slidable through a bracket fixed in thewindow frame,

llo

said device comprising a helical coil spring,

- two arms formed integral with said coils and A extremity ofone arm toengage the upper edge portion of the brace bar outwardly of the windowframe bracket, and-means on the eX- tremity of the other arm to engagean upri ht.

part of the window frame above said brac et 10 when said arms are sprungtoward each other.

2. The structure specified in claim 1 in .which said armsare adapted tobe sprung toward each whenwin upright plane, and said means on thelatter arm for engaging the Y Window frame comprises an integral part ofsaid arm extending vtransversely sideways from the arm` to engage thewindow framek and a linger pressing member formed onrsaid part for thepurpose described.

In testimonyl whereof I affix my signature.
